◆ Product Overview: 

 The shut-off valve, also known as the cut-off valve, is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface from leaking. When the medium enters the valve from under the valve flap, the resistance that needs to be overcome by the operating force is the friction force of the valve stem and the packing and the thrust generated by the pressure of the medium. The force of closing the valve is greater than the force of opening the valve, so the diameter of the valve stem is larger, otherwise the fault of the top bend of the valve stem will occur. 

 ◆ Nominal diameter: DN15-DN600 

 ◆ Valve body material: stainless steel, cast steel, carbon steel, forged steel 

 ◆ Manufacturing standard: GB/ANSI/JIS

Each process, facility, and environmental constraint has its own special requirements. Therefore, Kinko offers a comprehensive range of products that include different performance levels, pressures, functions, and materials.
